The MLX73290-M multi-channel RF transceiver IC by Melexis, addresses sub-GHz ISM bands from 300MHz to 960MHz. The IC features two RF channels 
The MLX73290-M multi-channel RF transceiver IC. Source: Melexiswith a programmable RF power transmitter and highly sensitive RF receive and full programmability via a serial peripheral interface (SPI).
The device is used in such applications as home/building automation, tire pressure monitoring (TPMS), automatic meter reading (AMR), alarm systems, passive keyless entry (PKE), medical diagnostics and telemetry. Power levels range from -20dBm to 13dBm and receiver sensitivity can attain -120dBm in a 15kHz bandwidth. The transceiver also handles heightened data throughputs given its data rate of 250kbps.
RF parameters such as number of channels, frequency resolution, output and frequency deviation can be adjusted to meet application criteria. Additional features include: support of on/off keying (OOK); binary frequency shift keying (FSK); minimum shift keying (MSK); Gaussian minimum shift keying (GMSK) and Gaussian frequency shift keying (GFSK) modulation schemes; power detectors augment radiated power performance during transmission; and an energy-harvesting interface that allows battery-less power supply.
The MLX73290-M is housed in 5mm x 5mm 32-lead QFN package and has an operational temperature range of -40°C to 105°C. Evaluation boards are also available.
